    Instagram has precise requirements for image dimensions. Using wrong sizes can result in automatic cropping or quality loss.

    Each publication type (post, story, reel, profile) has its own optimal dimensions to follow.

    This guide gives you all official sizes and best practices for perfect Instagram display.

    Dimensions for Instagram Posts

    Square: 1080 x 1080 pixels (1:1 ratio).

    Portrait: 1080 x 1350 pixels (4:5 ratio) - most engaging.

    Landscape: 1080 x 566 pixels (1.91:1 ratio).

    Minimum resolution: 320 pixels wide, but 1080 recommended.

    Dimensions for Stories

    Ideal size: 1080 x 1920 pixels (9:16 ratio).

    Safe zone: avoid text in the top 250 pixels (username) and bottom (replies).

    Stories are full screen on mobile.

    Dimensions for Reels

    Format: 1080 x 1920 pixels (9:16 ratio), same as Stories.

    Cover: 1080 x 1920 with central zone visible in feed.

    Duration: up to 90 seconds.

    Profile Photo

    Recommended size: 320 x 320 pixels (displayed at 110 x 110).

    Square format mandatory (1:1 ratio).

    Circular mask: watch for elements in corners.

    Tips for Optimal Quality

    Always use 1080 pixels wide minimum.

    4:5 portrait format takes more space in feed.

    Compress to JPEG 80-85% quality or WebP.

    Avoid text too small on mobile.
